The Brazilian Blow Dry application can not be done without a comb. The reason is, it is important that when applying the product that the excess is combed off each and every hair strand, and then again when the whole of the hair has been treated. Also, contrary to what some people think that applying extra product will give a better result, it won't. Overloading the hair with the product just makes for harder work when it comes to blow drying the hair and does not give the best final result. So please comb off that excess and don't apply more treatment than is needed, and let us know if you need a comb with your order.
